W250-2, Through-beam photoelectric sensor
Type
Part No.
> WSE250-2P1131
> 6044703
At a glance
• Very high sensing range in compact housing
• Versions for 10 - 30 V DC or 24 - 240 V DC/ 24 – 240 V AC voltage supply in
compact design
• Mounting bracket included in delivery
• Potentiometer with an easy-to-read positioning indicator for adjusting the sensing
range
• Operating mode (light/dark) selectable via control wire
• Cable or rotatable M12 connector
Your benefits
• Universal AC/DC voltage variants provide high performance and increased
flexibility in environments with limited space
• High performance reserve in harsh environmental conditions
• Mounting kit reduces installation time
• Operating mode (light/dark) is selectable via a control cable to reduce the number
of device variants
• Mounting compatibility - DC devices and AC/DC devices available in same design
